forensics-colorize binary package in Ubuntu Focal amd64

 forensics-colorize is a set of tools to visually compare large files, as
 filesystem images, creating graphics of them. It is intuitive because the
 produced graphics provide a quick and perfect sense about the percentage
 of changes between two files.
 .
 Comparing large textual files using a simple diff can produce a very big
 result in lines, causing confusion. On the other hand, diff is improper
 to compare binary files.
 .
 This package provides two command line programs: filecompare and colorize.
 The filecompare command is used to create a special and auxiliary input
 file for colorize. The colorize command will generate an intuitive graphic
 that will make easier to perceive the level of changes between the files.
